I have a couple of Armalites. One got rebarreled to an 18" medium weight Shilen/Rainier Ultramatch barrel in .308. It shoots well, consistently around 1"-1.25" with a variety of loads.
I also have a SASS that's never been able to do much under 1½", despite much fiddling with loads, trigger, big Nightforce scope, etc. I think I will make a 6.5 Creedmoor out of this rifle, although a really primo .308 bull barrel might shrink groups a lot as well. The rifle is heavy, and comes with adjustable gas block, so I think it will eventually get a can.
McGowan will build a Armalite pattern barrel, so will Krieger. I'll probably have Krieger do it as it's really annoying to have a really heavy rifle that isn't terribly accurate.
